This is driving me NUTS!!

I have had a severe muscle spasm (twitching) in my right thigh for FOUR DAYS NOW! It's about to make me CRAZY! It stops and starts ALL day and night long. Sometimes it's fast...sometimes its slower...and sometimes it looks like my leg is vibrating! I would say it does this about every 5 minutes and last night, it KEPT waking me up all throughout the night. Matt says "that is so weird. Something about that is not right." Grant says "I think there is a frog in there!" and Brooklyn says, "Oh, it's like there is a baby in your leg and its kicking!"
HA HA
Everyone has their theory...but I don't really know what to think. I've checked it out on the internet and all I can find is that it could be due to excessive caffeine (which is impossible given the fact that I rarely ever eat chocolate and I don't drink soda) or it could be due to a lack of nutrients and that a person with twitching should eat more fruits and veggies. Well, if I ate any MORE fruits and veggies than I am already eating..I think I'd throw up. I am eating them at almost every meal. Bluchk....
So...anyone have any suggestions or ideas? I have hit it, massaged it, pressed on it....nothing helps. As a matter of fact, it's going to town RIGHT now! ha ha
Seriously, it's like a creature has invaded my leg!!
